Many camera effects, including Duke Nukem-style security camera or Unreal-style skyboxes. Cameras can even replace the player view, allowing for scripted cutscenes or alternative gameplay mimicking a sidescroller.

Support for using features of every supported game in all of them -- for example, a Doom map can feature Strife conversations, Hexen scripting and actors that use Heretic codepointers.

Support for loading resources directly from ZIP or 7z files, making the use of the traditional WAD file format optional except for map lumps.
